Abstract

PURPOSE: To analyze the clinical and roentgenographic results of rheumatoid arthritis and osteoarthritis after cemented total knee arthroplasty with posterior cruciate retention. MATERIALS AND METHODS: Since 1989, 53 cases of rheumatoid arthritis and 454 cases of osteoarthritis were followed up for average 7.3 years(range 5-14 years) after cemented total knee arthroplasty with posterior cruciate retention. RESULTS: There was no statistically difference in KSS knee score(A: 88.5, B: 92.2), functional score(A: 73.2, B: 79.3), activity level(A: 76, B: 80), flexion contracture(A: 4.5 degree, B: 4.3 degree), tibiofemoral angle(A: 4.8 degree, B: 4.7 degree) and roentgenographic findings. There were hyperextension of 4 cases in group A and 3 cases in group B, but instability was not found. CONCLUSION: There was no significant difference in clinical and radiological results between the osteoarthritic and rheumatoid arthritic group after cemented TKR with PCL retention. Therefore, cemented TKR with PCL retention could be used as a valuable method in treating rheumatoid arthritis.
